[PATCH] netifd: bridge: set default value for igmp_snoop

[sotux82 at gmail.com]

From: Zheng Qian <sotux82 at gmail.com>

When luci unchecked the igmp snoop option for a bridge, it
just delete the igmp_snooping key from the config file.
So netifd can't change /sys/devices/virtual/net/br-lan/bridge/multicast_snooping from "1" to "0".

This patch will set a default value to false for the bridge
option to fix this bug.
